Verdict
The clearest difference is in-app purchases: TRILLION DSP at none against Laser Harp's 1. TRILLION DSP also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.0). Laser Harp's advantage is update cadence (every 2 months vs every 9 months). On price and device support there is nothing between them.
